1 OVERVIEW

1.1 Sensor Overview

The VS6552 VGA image sensor produces raw

VGA digital video data at up to 30 frames per sec-

ond. The image data is digitized using an internal

10-bit column ADC. The resulting 10-bit output

data includes embedded codes for synchroniza-

tion. The data is formatted and transmitted over a

fully differential link. The data is accompanied by a

qualifying clock that is transmitted over an identi-

cal fully differential link.

The sensor is fully configurable using an I2C inter-

face.

The sensor is optimized for high volume mobile

applications

1.1.1 Typical Application - Mobile Application

The VS6552 is an image sensor, it should be used

conjunction

with

the

STMicroelectronics

STV0974 companion processor. The coprocessor

and the sensor together form a complete imaging

system.

The sensors main function is to convert the viewed

scene into a data stream. The companion proces-

sor function is to manage the sensor so that it can

produce the best possible data and to process the

data stream into a form which is easily handled by

up stream mobile baseband or MMP chipsets.

The sensor supplies high speed clock signal to the

processor and provides the embedded control se-

quences which allow the co processor to synchro-

nize with the frame and line level timings. The

processor then performs the color processing on

the raw image data from the sensor before supply-

ing the final image data to the host.
